I've been saddled with GAD for 50 of my 65 years on this earth. Finding this forum has helped me with a much greater but nowhere near complete understanding of Hypochondria. I'm aware of a couple differences between our anxiety disorders. I get many, many anxiety-related physical symptoms. The first difference is being able to respect/accept when my doctor tells me that the symptoms that I've related to him are anxiety-related. Another difference seems to be how I approach my many physical symptoms that consistently crop up. A hypochondriac seems to approach their physical symptoms by assuming they are real first and trying to fit the symptom(s) to a major disease. As a GAD sufferer, I'm lucky that my thinking first assumes that any of my physical symptoms are anxiety-related. I am not able to fully relate to what a hypocondriac suffers through. I know what I go through and wouldn't wish any anxiety disorder on anyone, I think including my enemies.
